MAX4546CSE

Analog Switches - Special Purpose Overview

The MAX4546CSE is a dual, low-voltage bidirectional RF/video switch IC in a 16-pin SOIC package. It contains two SPST switches (one normally open, one normally closed) with a maximum on-resistance of 20Ω and a -3dB bandwidth of 300MHz. Operating from ±2.7V to ±6V dual supplies or +2.7V to +12V single supply, it features off-isolation of -80dB at 10MHz and crosstalk of -80dB at 10MHz. The device operates within a temperature range of 0°C to +70°C.

Analog Switches - Special Purpose Feature Summary

• Bidirectional signal switching capability for RF and video applications
• TTL- and CMOS-compatible logic inputs for versatile control
• Break-before-make switching action to prevent signal shorting

Analog Switches - Special Purpose Applications

• RF switching in communication systems
• Video signal routing and multiplexing
• High-speed data acquisition systems
• Test and measurement equipment
• Automated test equipment (ATE)

Analog Switches - Special Purpose Procurement Notes

Verify the 'C' suffix indicates the commercial temperature range (0°C to +70°C). Confirm the 'E' suffix denotes the standard SOIC-16 surface-mount package. Ensure the component is lead-free if RoHS compliance is required for the specific manufacturing batch.

Analog Switches - Special Purpose Selection Notes

Select this part when dual independent SPST switching is required. The MAX4546 differs from the MAX4545 (quad SPST) and MAX4547 (dual SPDT). Verify that the 20Ω on-resistance meets system loss requirements and that the 300MHz bandwidth supports the target signal frequencies.

Analog Switches - Special Purpose Part Context

The MAX4546CSE belongs to the MAX4545/MAX4546/MAX4547 family of low-voltage T-switches. These devices are designed for high-frequency performance in 50Ω and 75Ω systems. The CSE variant specifically provides the commercial temperature grade in a narrow SOIC footprint.

Analog Switches - Special Purpose Replacement Considerations

MAX4546ESE+ offers the same functionality in an industrial temperature range (-40°C to +85°C). MAX4546CPP provides a plastic DIP package option. MAX4547 variants offer SPDT configurations instead of SPST.
